Description
Colin Vullioud and six co-authors found chemical marks on DNA that shift as male cheetahs gain territory in a 2026 paper. Namibian cheetahs have very low genetic diversity, which should limit adaptation. Yet males pass through a clear life change, from roaming floaters to territory holders, with shifts in shape, movement, and aggression.
The team sampled the same males before and after the change and compared DNA methylation, a gene-tagging system. Territorial males showed widespread extra methylation. The changed genes serve head and brain development, signaling, and ion transport, matching the visible shifts. The authors offer rare wild evidence that epigenetic marks help a genetically uniform species stay flexible.
